To (LZZ whom it may concern.-

Be itknown that we, JOSEF I-IEROLD and CARL I-IEROLD, subjects of theEmperor of Austriadlungary, residing at Brunn,Austria- Hungary, haveinvented certain new and useful Improvements in Round Looms; and we dohereby declare the following to be a full, clear, and exact descriptionof the invention, such as will enable others skilled in the art to whichit appertains to make and use the same.

This invention has been patented in the following foreign countries:Austria, issued January 2, 1897, -No. 47/6, and March 24, 1897, No.47/1,006; England, issued May 8, 1897, No. 5,332,,Belgiunt1, issuedMarch 15, 1897, No. 126,586; Belgium, patent of addition,issued April30,1897,No. 127,581; France, issued June 2, 1897, No. 264,399; Italy,issued June 9, 1897, Reg. Gen, XXXIII, No. 44,409, Reg. Att., LXXXVII,No. 22; Switzerland, issued September15, 1897, No. 13,974; Luxemburg,issued March 4, 1897, No. 2,771; Hungary, issued October 5, 1897, No.9,695; Germany, issued February 25, 1898, No. 96,270, and March 1, 1898,No. 96,271, and Canada, issued November 22, 1897, No. 58,189.

This invention relates to a new or improved construction of circularloom by means of which a greater amount of cloth can be produeed withoutany increase of motive power than with any of the present ordinary andcircular power-looms. In our improved circular loom this is accomplishedby the following arrangements: First, several shuttles are at worksimultaneously on the same Web, and, second, the formation of the shed,the propulsion of the shuttles, and the beating up of the weft-threadsare carried on without intermission.

The invention will be fully described with reference to the accompanyingdrawings.

. Figure 1 is afront elevation, in part section; Fig.2, a sideelevation, in part section, of the loom, omitting details relating tothe opening of the shed and the beating up of the Weftthreads to theweb; Fig. 3, a vertical section No. 126,586; in England 1897, XXXIII,44,409, and LXXXVII, 1897,170. 9,695,- in Canada November 22,1897, andMarch 1,1893,1\To.96,271.

Fig. 9 shows the way inwhich the spring-rings are connected. Fig. 10 shows an outline of theheddles G and the tops of the reeds; Fig. 11, an enlarged section online a: on, Fig. 10; Fig. 11, an enlarged section on line yy, Fig. 10;and Fig. 12, the toothed flanges R, the flange Rec with the eccentricflanges cab 0371 00b and the levers bl bl in outline.

By reference'to the drawings the most important arrangements of ourcircular loom are seen to be, first, the opening of the shed; second,the shuttles; third, the lever arrangement for beating up theweft-threads to the web; fourth, the Weft-guard, and, fifth, the drivingarrangements of same.

The shaft W, journaled in the bearings Z and driven by the pulley P,Figs. 1 and 2, transmits its motion, by means of the beveled wheels K K,to the vertical shaft W. The latter is .journaled' at one end in thecollar Z in the cross-piece T and at the other end in the collar Z inthe bell-shaped piece H on the cross-piece T and the rings above thesecollars Z Z serve as supportiligsurfaces.

On shaft W, underneath the cross-pieces T, the boss Nis fixed, and onthis the electromagnets (the number of which in the present case isfour, Fig. 6) are secured. These electromagnets receive the current fromsome source of current through the intermediary of a sliding contactlocated on, but insulated from, the shaft w. The contact consists of acollar on", made of insulating 1naterial-such as wood, hard rubber,ebonite, or the like upon which two brass rings m m" are fixed. Astationary brass spring m rubs against each of these rings. The wires mm leading from the source of current, are connected with the supports mof these cohtactsprings. From the rings conducting-wires m m lead to thesuccessive magnet-coils E. On the crosspieces T the bearings r of therollers r, revolving on the pin T are fixed, and these rollers projectinto the groove r of the toothed flange R, which they support and enableto run easily and steadily, Fig. 3. Instead of roller-bearings for thetoothed flange ballbearings may be advantageously used.

The vertical shaft V rotates in the bearin gs Z If, Fi 2, fixed on thecross-pieces T T, and the toothed wheel Z, firmly fixed upon thevertical shaft Wiengages with the toothed flange R, the effect of whicharrangement is to cause the toothed flange-It to make the same number ofrevolutions as the shaft WV. Shaft W is driven by means of the beveledwheels K K from shaft WV, so that shaft W, shaft V and the toothedflange are all interconnected. The warp is carried from the warp-beamsKB, (the number in the present case being four,) weighed in the usualway over the beams O O G to the heddles g, and the warp -threads 01 amust, in order to be properly distributed, first pass the cross-rin gs hh. The heddles, Fig. '7 which have an eye g in the center, and thenumber of which corresponds to the number of the warp-threads, arefitted radially to the shaft W. One end of the heddles is deflecteddownward at a right angle and carries a roller gr, while the other end,on account of being supported radially, is suitably flattened. Thedeflected ends of the heddles g are carried into the suitablyshapcdgrooves X X of the rings X X The number of these eccentric-rings, on thetopmost of which a cover X is put and which are interconnected byscrews, corresponds to the warp-and-wcft arrangement of the web, and inthe present instance two eccentricrings are required. As shown in Fig.4, the grooves X X of the superimposed eccentricrings X X intersect eachother, and the number of these intersections must correspond with thenumber of the shuttles. The undermost eccentric-ring X is firmlyconnected by the arms Y and the ring X by means of screws with thetoothed flange B. At the other ends the heddles g are carried betweenthe vertical metal plates B of the reed-flanges B 13, Figs. 10, 11, and11,wl1ich are placed upon the spring-rings Z) If and kept apart fromeach other by intervening pieces. By this means the heddles areprevented from following the rotary motion of the eccentric-rings X XThe heddles g slide on ring Z) or over the little pulleys or ring I)between every two metal plates. One portion of the metal plates 13 islengthened at the top and is there fastened by screws or rivets to theshoulders D D of the bearingpieces D D, the former of which is screwedto the cross-pieces T and the latter to the beltshaped pieces a. Oneportion of the metal plates B is lengthened at the bottom and connectedby the metal pieces I) with the cylinder-casing f, thus providing a firmbearing for the latter. The loose temple-ring O, which is held 011 thelower end of the shaft W by a ring, is unaffected by the rotary motionof the shaft 7 and has a groove 92 011 the upper side, in which anisolated contactring is fixed. Further, the temple-ring O carries acylinder-casing f, made of non-magnetic material, which on one sideserves as a supporting-surface for the warp-threads pressed inward bythe shuttles S and on the other side prevents the shuttles beingcompletely drawn to the electromagnets E. The latter are shaped in sucha way that they can easily move inside the cylinder-casing f.

The shuttles S, which are made of some light material-such as wood,paper, &c. are suitably adapted in shape to the box, which is round andat the bottom runs to a point, and are provided with a cavity a for thereception of the cop or spool. On the side which is turned to thecasingf the shuttles are fitted with a metal plate (iron) 81) formagnetic effect and run with their pairs of rollers er and 51" over thewarp-threads ad jacent to the casing f and with their pair of rollers.91" on the ends A of the levers 6Z projecting into the box. Through thehole S, Fig. 6, the weft-thread is carried over the guide-pin O to theweb.

On the inner side of the toothed flange R a flange R00 is fixed, onwhich the pieces 56b 00b 50b forming the eccentric, are screwed. On thecross-pieces T the brackets D are fixed under the nether flange 00b, andon these brackets are screwed the plates Y,which are connected with thebearing-pieces q of the levers bl. To the holes of the radiallyplacedbearings q a spring-ring M is fixed, on which the bent levers bl areloosely placed. The arms a of the levers bl, each provided with roller aproject into the curved groove 1, formed by the flanges 00b and 5011 andin the same way the arms a fitted with rollers a of the levers biproject into the windinggroove 2, (see also Fig. 5,) formed by theflanges 00D and 0:6 On the other side the flat arms a of the levers Mproject underneath the shuttles S and above the templering 0, betweenthe warp-threads, into the box.

In order to stop the rotary loom when a weft-thread is broken or hascome to an end, a weft-guard is placed on the standard S n11- der thebelt-pulleys P and Q. This guard, Figs. 2 and 8, consists of a steelspring Gf, fixed to the standard S, into the slit se, of which the pinGb in the lower end of the fork G, pivoted into the bearing Ga, iscarried. The steel spring Gf intersects the slot 86 of the plate $15 onthe standard S, round the pin 86 of which the angular lever he isprovided. The arm hs of this angular lever projects on one side into theopening of the electromagnetic bobbin fixed on the plate st, while thesteel spring Gf comes into'contact with its curved lower end 72.5 whenthe loom ,is started. The coil SE is put in the circuit in the followingmanner: Conducting-wires 3 and A branch off, respectively, from each ofthe wires m m leading from the source of current to the electromagnetsE. These wires 3 and at lead to the levers bl which are electricallyconnected by the manner in which they are mounted and to thebinding-post 1 of the coil 5E. The other binding-post 2 of said coil isconnected by the conducting-wire 5 with the insulated copper ring 06 inthe groove 07. of the temple-ring O. The stroke of the bell-crank orangular lever hs is arrested by the pin si and the angular lever hs isheld in the position shown in the drawings by the spring sf.

The rotary loom works as follows: Then the warp-threads n n are drawn inthe manner shown and described, the shed formed by the heddles g, andthe shuttles S put into the box, the magnet E is energized by a currentthat passes through the wire m, the upper spring m the ring m, the wirem all the magnet-coils E, the wire m", the ring m the lowercontact-spring m and the wire m back to the line. During the rotation ofthe shaft to the stationary contact-springs slide without interruptionagainst the rings m 172 so that the magnets E are constantlyenergized,and the shuttles are carried along with the motion of the shaft W by thecontinuouslyoperating attraction of the electromagnets, which causesthem to run along the race and insert the weft-threads. At the same timethe position of the shuttles S and of the eccentrics X X is so arrangedthat behind each shuttle at the spot which it has just traversed animmediate change of shed takes place, which is effected in the presentarrangement by the deflected ends of the heddles g in the inner part ofthe groove X passing into the outer part of the groove X by which meansthe warp-threads n, hitherto formingthe right part of the shed, arecarried outward and now form the left part of the shed. (Refer to Figs.1 and 2.) At the same time the warp-threads n also change their positionas the deflected ends of the heddles g are carried from the outer partof the groove X to the inner part of the same.

As in the accompanying illustration, the groove-courses X X intersecteach other four times, the shed is divided into four parts, and thewarp-threads n n run in the third division of the shed in exactly thesame way as the first, whereas in the second and fourth divisions of theshed they are reversed-that is to say, if, forexample, the warp-threadsform the right part in the first and third di visions of the shed theyform the left in the second and fourth, and so on. It should bementioned here that the number of eccentric rings X X that of theintersections of the grooved courses X and that of the shut tles, areregulated according to the nature of the material required.

As soon as the weft-threads have been car-.

ried over the lever-arms a they require beating up to the web, which iseffected by the arm a of the lever bl coming in the first place into thedescending curve of the groove 1, Fig. 5, when the lever bl is turned inthe direction of the arrow, Fig. 3. 'The latter carries the lever blwith it and throws the latters arm a out of the shed. The relativepositions of the downward curves of the grooves 1 and 2 are now suohthatafter the commencement of the lever motion described the arm a of thelever bl comesinto the curve of the groove 2 when the lever bl is turnedin the direction of the arrow 2, Fig. 3. The lever-arm Cl has in themeantime enteredthe straight part of the groove 1 and turned the,

levers bl bl in the direction of the arrow 3, Fig. 3, when the arm ofthe latter again enters the shed above the inserted weft-thread, as itsarm a is still in the curve of groove 2. The lever-arm a now begins topass the ascending part 2 of the curve in the groove and thus turns thelever bl back into its original position, and consequently its arm abeats up the last shot to the web and leaves the way clear for thefollowing shuttle. As there are always a large number of theradially-placed levers bl bl a part of the lever-.

arms a a always pass the curves of grooves 1 and 2, so that the beatingup of the weft is going on continuously. The curves of the grooves 1 and2 are so arranged that the weft is immediately beaten up by thelever-arms a when, after a shot has been inserted, a change of shed hastaken place. Of course the position of the intersections of the groovesX X of the eccentrics X X and the curves of the grooves 1 and 2 of theflanges Xb Xb Xb can be so arranged that the beating up of the weft tothe cloth takes place firstand the change of the shed afterward. Thecurves of the grooves 1 and 2 then, from the intersections of thegrooves, courses X X of the eccentrics X X and a double beating of thelever-arms A on the web can easily be attained by dou ble bends in thegrooves 1 and 2.

The web passes from the temple-ring C between the tension-rollers clcl,the axles cl (l of which revolve in the bearings (l (1 The roller d isdriven from the main shaft WV by means of the strap-pulleys pp, axle Wscroll O, and the scroll-wheel l, fastened 011 the'roller-axle cl, whichengages with the scroll.

After the tubular web has left therollers clrl it wraps itself automatically in consequence of itsfriction against roller cl on rollerL, which re volvcs on the bracketsThe stoppage of the, loom when the weftthread breaks-or a spool becomesempty is effected by the lever-arms A falling by their own weight andthat of the following shuttle into the opening formed near the end ofthe weft-thread and coming into contact with the ring 06, Fi 3, when thepiece 713 of the angular lever hs is drawn into the spool 8E, Fig. 8,and the spring Gf is released from the nozzle 715 The spring 91) movesin consequence of its elasticity in the direction of the arrow, Fig. 2,thus turning the fork G, which pushes the strap from the pulley P to theloose pulley L.
